The word igneous comes from the Latin word for fire. However, the name is inaccurate. The rocks are not created with flames. Instead, they are created when magma cools and hardens. Magma is hot molten rock found deep in the earth. Igneous rock is either intrusive or extrusive. It is intrusive when it forms inside the earth's crust. It is extrusive when it is formed above the earth's surface.

Select the sentence from the passage that supports the idea that temperature is an important factor in the formation of igneous rock.

Explanation:

If a 3.0 (pg) sample of curium-245 has a half-life of 8500 years, then the conclusion which can be drawn is the curium-245 sample will have a mass of about 1.5 pg after 8500 years

Half life time is that time after which initial concentration of reactant becomes half of the initial.

Given that initial concentration of curium-245 = 3pg

After half life time concentration of curium-245 = 1.5pg

Hence, the curium-245 sample will have a mass of about 1.5 pg after 8500 years is the conclusion.

The reaction of acetic acid and sodium chloride produce hydrogen chloride gas and sodium salt of acetic acid. Thus the penny may change its colour by the gas and the evolution of a gas can be observed. Thus option A is correct.

Acetic acid is a weak acid with the formula CH₃COOH. It is the simplest carboxylic acid or organic acid after formic acid or HCOOH. Diluted acetic acid is commonly used as vinegar.

Acetic acid reacts with basic or alkaline substances forming its salt. It can also reacts with salts such as sodium chloride producing sodium salt of acetic acid as written below:

[tex]\rm NaCl (aq) + CH_{3}COOH(aq)\rightarrow CH_{3}COONa (aq) + HCl (g)[/tex].

Hydrogen chloride gas is formed in the reaction and and its evolution can be observed during the reaction as bubbles. The penny dropped in the solution may change its color because the HCl formed will reacts with the metal and forms the hydrogen gas and metal halide.

Hence, the penny change its colour and hydrogen gas is evolved. Thus, option A is correct.

For an atom to be neutral, it has to have the same amount of protons and electrons. Because protons and electrons have opposite charges, when there is an equal amount of them they balance each other out

The diagram that represents an electrically neutral atom is:

Option D

Whenever a molecule has an equivalent number of electrons and protons, it has an equivalent number of -ve electric charges (the electrons) and +ve electric charges (the protons). The all-out electric charge of the 0 is thusly zero and the particle is supposed to be unbiased.

Thus, option D is correct.

Mid-ocean ridges are most likely to create at the boundary where the seafloor is spreading. Therefore, option D is correct.

A mid-ocean ridge can be defined as a seafloor mountain system generated by plate tectonics. Mid-ocean ridge has a depth of about 2600 m and rises about 2000 m above the deepest portion of an ocean basin. Seafloor spreading happens along a divergent plate boundary.

The rate of seafloor spreading evaluated the morphology of the crest and width in an ocean basin. The formation of new seafloor can occur from the mantle in response to plate separation.

Mid-ocean ridges can be connected through plate tectonic boundaries and the trace of the ridges across the seafloor appears to be the seam of a baseball. The mid-ocean ridge system can be described as the longest mountain range on the surface of the Earth, reaching about 65,000 km.

Cell Membrane Function: The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Description:The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Nucleus Function:The nucleus has very important roles to play. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.

Description: The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

Explanation:

Answer:

The cell membrane is the semipermeable membrane of a cell that surrounds and encloses its contents of cytoplasm and nucleoplasm. The cell membrane separates the cell from the surrounding interstitial fluid, the main component of the extracellular fluid

A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.
