which one of the following groups are decomposers a. algae b. protist c. fungi d. green plants e. photosynthetic bacteria?
Answer:
c. fungi
Explanation:
Decomposers are organisms that breaks down dead and decaying matter in nature. They derived their nourishment by breaking down other complex organic matter.
Fungi are a group of organisms that are mainly decomposers.
They recyclers in nature.
Green plants and photosynthetic bacteria are similar in that they obtain nourishment by the use of light to initiate the reaction between carbon dioxide and water.

How can the law of conservation of
mass for a chemical reaction be expressed?
Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Explanation:
How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.

Explain the process of ionic bond formation between K
(potassium, a metal) and Br (bromine, a nonmetal).
I
Answer:
Metals transfers electrons to nonmetals. So K transfers one electron to Br because K is located at 1A in the periodic table. Br has seven electrons, now both K and Br are stable by gaining and losing one electron. The transfer of electrons makes metals to become positive ions and nonmetal to become negative ions. When an ionic bond is formed, the charges attract each other.
Answer: Metals transfers electrons to nonmetals. Potassium -K transfers one electron to bromine- Br because K is located in group 1A on periodic table. Br has seven electrons and located group 7A. Both K and Br stable by gaining and losing one electron. The transfer of electrons makes metals to become + positive ions and nonmetal to become - negative ions. An ionic bond is formed, the charges attract each other.
Explanation: Metals donate, or transfer, electrons to the nonmetal.
The transfer of electrons creates a positive ion and a negative ion.
An ionic bond is formed when the charges attract each other.

Explanation:
Carbon Monoxide is a toxic gas that is colorless and tasteless. How many moles of CO are in 1 L of the gas at STP?
28 moles
0.045 moles
22.4 moles
0.224 moles
Answer:
0.045 moles
Explanation:
Given data:
Moles of CO = ?
Volume of gas = 1 L
Temperature and pressure = standard
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
n = PV/RT
n = 1 atm× 1L / 0.0821 atm.L/mol.K × 273 K
n = 1 atm.L / 22.41 atm.L/mol
n = 0.045 mol

Answer:
Chemical Family means a group of elements in the Periodic Table or, more commonly, compounds that share certain physical and chemical characteristics and have a common name.
A period in the periodic table is a row of chemical elements.
metalloid is an element (e.g. arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid nonmetals or semiconductors.
PLEEEASSEEEE HELPPPPP!!!!!Take some time to research a utility plant. If there is one in your area, you may even visit it.
Otherwise, look up a type of plant that produces energy - such as a nuclear power plant, a
hydroelectric plant, or a coal-burning plant. Find out what energy resources are brought into the
plant. Then find out what energy and what "waste" is produced by the plant. Describe how the
two Laws of Thermodynamics apply to what you find out in your research. Be thorough. You will
be using the information you gather to engage in a debate with your class about
thermodynamics.
Answer:
There are four laws of thermodynamics that define fundamental physical quantities (temperature, energy, and entropy) and that characterize thermodynamic systems at thermal equilibrium.

Write a complete balanced equation for the following reaction:
magnesium metal reacts with oxygen gas
Explanation:
Given species:
Magnesium metals = Mg
Oxygen gas = O₂
Magnesium metal and oxygen gas are the reactants in this chemical process,
2Mg + O₂ → 2MgO
The product of the reaction is MgO because both oxygen and magnesium are divalent.
This reaction is called a combination reaction where two species combines to form a single compound.

I already answered number one, so I'll do number two. A turbine is a machine that spins in order to create energy or electricity, in some cases. The turbine collects the wind and it flows throughout the body of the turbine, where the machine then forms it into electricity.
Answer: 1. Generating energy is the meaning of process, which generates the electric power coming from sources of foremost energy. 2. A turbine is a machine that is for producing constant power, which works by a wheel or rotor, consisting of vanes, made to spin by speedy movement of steam, gas, air, water, etc. Due to this process, it allows for energy to be produced.

An object has a mass of 26.94 grams and a volume of 2.568 cubic centimeters. What material is it likely to be
made of?
Substance iron gold silver copper
Density (g/cm) 7.874 19.32 10.49 8.92
a. Silver
c. Iron
b. Gold
d. Copper
Answer:
a) silver
Explanation:
Given data:
Mass of object = 26.94 g
Volume of object = 2.568 cm³
Which subject is this = ?
Solution:
Formula:
d = m/v
by putting values
d = 26.94 g/ 2.568 cm³
d = 10.49 g/cm³
Densities of objects: g/cm³
iron = 7.874
gold = 19.32
silver = 10.49
copper = 8.92
Thus, given object is silver.
What is the relationship between an object's mass and its ability to pick up speed, or accelerate?
Answer:
It is momentum
Since momentum is proportional to the product of mass and velocity
Answer:
The greater the object's mass, the longer it takes to pick up speed or accelerate. There is an inverse relationship between mass and acceleration/picking up speed.

How many oxygen atoms are in 163 g of aluminum sulfate? 
Answer:
3.44 × 10²⁴ atoms of oxygen
Explanation:
Step 1: Calculate the moles corresponding to 163 g of Al₂(SO₄)₃
The molar mass of Al₂(SO₄)₃ is 342.15 g/mol.
163 g × 1 mol/342.15 g = 0.476 mol
Step 2: Calculate the molecules in 0.476 moles of Al₂(SO₄)₃
We will use Avogadro's number: there are 6.02 × 10²³ molecules of Al₂(SO₄)₃ in 1 mole of Al₂(SO₄)₃.
0.476 mol × 6.02 × 10²³ molecules/1 mol = 2.87 × 10²³ molecules
Step 3: Calculate the atoms of O in 2.87 × 10²³ molecules of Al₂(SO₄)₃
According to the chemical equation, the molar ratio of Al₂(SO₄)₃ to O is 1:12. The atoms of O are 12/1 × 2.87 × 10²³ = 3.44 × 10²⁴.

When does the number of electrons be greater than the number of protons?And give examples.
Answer:
This accepting atom will then become an anion. The anion has more electrons than protons. This means that some of the electrons will not be canceled out, giving the atom an overall negative charge.
If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. If there are equal numbers of protons and electrons, then the object is electrically neutral.

If alcohol has a density of 0.84 g/ml, would it float or sink in a cup of water (density of 1.00 g/ml)?
Denser materials will always sink below less dense materials.
So in this case, the alcohol would float since it has a lower density.
