Copper(II) Phosphite is the IUPAC name of the given compound. Ionic compounds don't get prefixes like di-, tri- etc.

International Union of Applied and Pure Chemistry is referred to as IUPAC. The IUPAC establishes the standards for the atomic weights that are shown on the periodic table and is the acknowledged authority for chemical nomenclature, measurements, including atomic mass values. Although IUPAC produces publications in many scientific domains, including physics, biology, and chemistry, it is most recognised for its work standardising nomenclature in the chemical sector. Standardising code names for nucleotide base sequences is one of the significant things the IUPAC has achieved in these areas. Copper(II) Phosphite is the IUPAC name of the given compound.

Answer: chlorophyll

Explanation:

The substance that plants use to capture light energy from the sun is referred to as chlorophyll.

The chlorophyll is a colored pigment that is used by the plants for photosynthesis. The function of the chlorophyll is that it absorbs the energy from the sun which is then turned into a chemical energy.

Explanation:

similarities: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal element

differences:  A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.

a larger bullet weighs more then a smaller bullet so the smaller bullet goes faster.

Answer:

Explanation:

Momentum is dependent on mass and velocity. So, the smaller bullet can be moving at a much greater speed than the larger one.

Answer:

When 2 or more pure substances are mixed together they form a mixture. If the mixture has its different components mixed evenly within the substance it is a homogeneous mixture. Whereas if the mixture has its different components mixed unevenly within the substance it is a heterogeneous mixture

Answer:

El Niño

Explanation:

The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.

El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years

During El Niño, the  surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.

El Niño brings rainfall nd flooding to South America and droughts in the western United States

Answer:

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A.

Explanation:

Answer:

Option D.

Explanation:

Let's balance the hole reaction by the ion electron method.

Al (s) + Cr(NO₃)₂ (aq) – Cr (s) + Al(NO₃)₃ (aq)

We know that oxidation state at ground state is 0.

We determine the half reactions:

Al  ⇆   Al³⁺  +  3e⁻

Aluminum increase the oxidation state. This is the oxidation.

Cr²⁺ + 2e⁻  ⇄   Cr

Chromium decrease the oxidation state. It changed from +2 to 0.

This is the reduction. In order to balance the half reactions, we need to multiply by 2 and by 3. In that way, we can cancel the electrons:

(Al  ⇆   Al³⁺  +  3e⁻) . 2

(Cr²⁺ + 2e⁻  ⇄   Cr) . 3

We sum the half reactions:

2 Al + 3 Cr²⁺  +  6e⁻  ⇄  2Al³⁺  +  6e⁻ + 3Cr

We cancel the electrons, so now the balanced reaction is:

2Al + 3Cr(NO₃)₂  →  3Cr  + 2Al(NO₃)₃

Final answer: 6 electrons are transferred in the redox reaction.

In this experiment, you made observations of the reactant and the product.

You used these observations to write the balanced chemical equation.

The symbolic representation of chemical reaction is called chemical equation.The chemical equation should be balanced.

Explanation:

edg 23'

Answer:

2 liters of HBr is needed to completely react with the 50 g of salt.

Explanation:

First of all, we determine the reaction:

2HBr + CaCO₃ →  CaBr₂  +  CO₂  + H₂O

We need to calculate, moles of carbonate in order to state the stoichiometry (1:2)

50 g . 1mol / 100.08g = 0.499 mol

1 mol of salt need 2 moles of acid to react, according to stoichiometry

Then, 0.499 moles of salt, will react with (0.499 . 2)/1 = 0.999 moles

As we have the [HBr], we can calculate the volume.

M = mol/L → we replace → 0.50 mol/L = 0.999 mol /L

L = 0.999 mol/0.50 mol → 1.99 L ≅ 2L

Answer:

A catalyst is anything that alters the rate of the reaction same as an enzymes that adds to the process in a human body which stops working when a person has fever

Answer:

Enzymes are proteins functioning as catalysts that speed up reactions by lowering the activation energy. A simple and succinct definition of an enzyme is that it is a biological catalyst that accelerates a chemical reaction without altering its equilibrium. ... In the overall process, enzymes do not undergo any net change.
