Answer: A : Convergent
Explanation:
Is there a phobia for chemical reactions specifically?
Answer:
chemonoia
Explanation:
Many people have a strong fear of “chemicals” that belies the evidence. It's called chemonoia – and it may be damaging their health. If you were paranoid, you might think there really was something in the water that's damaged our sense of reason.
Pure gold has a density of 19.3 g/ml. A gold bracelet has a mass of 412 g and a volume of 22.4ml. Is the bracelet pure gold? Explain.
Answer:
[tex]\boxed {\boxed {\sf No, \ the\ densities \ aren't \ equal}}[/tex]
Explanation:
First, let's find the density of the gold bracelet.
Density can be found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the bracelet is 412 grams and the volume is 22.4 milliliters.
[tex]m=412 \ g\\v= 22.4 \ mL[/tex]
Substitute the values into the formula.
[tex]d=\frac{412 \ g}{22.4 \ mL}[/tex]
Divide.
[tex]d=18.3928571 \ g/mL[/tex]
Let's round to the nearest hundredth.
The 2 in the thousandth place tells us to leave the 9 in the hundredth place.[tex]d \approx 18.39 \ g/mL[/tex]
The density of the bracelet is about 18.39 grams per milliliter.
Now, let's compare the bracelet's density to pure gold's density.
[tex]bracelet= 18.39 \ g/mL\\pure \ gold=19.3 \ g/mL[/tex]
It's quite clear that the two values are not equal. Therefore, the bracelet cannot be made of pure gold, because it's density doesn't match pure gold's.

What is meant by the statement ' protential difference between point A and Point B in an electric circuit is 1 V' ?
Answer:
The potential difference is considered as the change in terms of voltage or Del V. It is measured in terms of voltage so that statement got the name voltage change between point A & B is 1. It means that I joule of work is carried out for moving the 1 coulomb of charge from the point A to B.

if 100.0 grams of copper (cu) reacts completely with 25.0 grams of oxygen, how much oxygen will completely react with 140 grams of copper?
Answer:
35 grams of oxygen
Explanation:
The law of constant proportion or composition states that the elements that combine to form a chemical compound combine in fixed whole number ratios.
Therefore, the ratio of the that make up any pure sample of a given compound are present in the same mass ratio
The given parameters are;
The mass of oxygen that reacts completely with 100 grams of copper, (cu) = 25.0 grams
Therefore;
1 gram of copper completely reacts with 25/100 = 1/4 grams of oxygen
140 grams of copper will completely react with 140 × 1/4 = 35 grams of oxygen
∴ 35 grams of oxygen will completely react with 140grams of copper.
c) What is the net charge of the nucleus?

Explain why and argon atom would not bond with other atoms?
Answer:
Argon is a noble gas. Noble gases do not bond with others atoms easily because they already have a full outer electron shell :)
use the periodic table to find the number of valence electrons for calcium (Ca) aluminum (Al) rubidium (Rb) oxygen (O) sulfur (S) and iodine (I).
then use that information to predict the formula for each of the following compounds: Calcium oxide, aluminum iodide, rubidium sulfide, and aluminum oxide.
Answer:
Calcium (Ca) => 2
Aluminium (Al) => 3
Rubidium (Rb) => 2
Oxygen (O) => 2
Sulphur (S) => 2
Iodine (I) => 1
Formulae
Calcium oxide : CaO
Aluminium iodide : AlI3
Rubidium sulphide : RbS
Aluminium oxide : Al2O3

how does newtons three laws effect bowling?
Answer:
The laws allow the ball to move
Explanation:
first law - an object in motion (the bowling ball) will go until the friction of the lane stops it
second law - f=m*a, the force in which you bowl, equals the mass of the ball, times the acceleration of the ball
third law - the action, is you bowling the ball and it rolling down the lane, the reaction is the friction slowing the ball down. Another action is the ball hitting the pins, the reaction is the pins falling.
I hope this helps.

The temparature of boiling water cannot be measured by _______ temparature
Answer:
Temperature of boiling water cannot be measured by a Clinical thermometer The reason behind this is that the range of clinical thermometer varies between only 35° C to 42° C.
Answer:
It cannot be measured using clinical thermometer.
Explanation:
Thermometer is an instrument use for measuring temperature that is the degree of hotness and coldness
The temperature of boiling water cannot be measured by clinical temperature or thermometer because it can only measure temperature ranges from 30 to 40°c and the temperature for boiling water is 100°c.

What are the properties of solids? Of liquids? Of gases?
Answer: Hope this helps.
Gas: assumes the shape and volume of its container particles can move past one another, compressible, lots of free space between particles.
Liquid: assumes the shape of the part of the container which it occupies particles can move/slide past one another, not easily compressible, little free space between particle.
Solid: retains a fixed volume and shape, rigid - particles locked into place, not easily compressible, little free space between particles.
how dose ice melt? how dose it form?
6. Geologists in Egypt and Ethiopia are comparing rock samples from rocks
found in the two countries. They are sharing information about the rocks to
figure out whether they are the same or different types of rock. The information
is as follows: Rock A formed from small pieces of rock. Rock B formed from liquid
rock in a different place. Rocks A and B formed at about the same time. Are
Rocks A and B the same or different types of rock? The rocks are
Answer:
Both are different.
Explanation:
Both rocks are different from one another because both formed from different types of rocks. Rock A was formed from small pieces of rock while on the other hand, Rock B was formed from liquid rock so they both have different sources of rocks from which they were formed. Forming at the same time does not show that they are similar to each other, it is their source which decides that they are similar or different.
