Answer:

The answer to your question is A. Decomposition

Explanation:

In the picture, we can observe that there is only one reactant that after the reaction are formed two products.

We observe that this is a decomposition reaction.

It is not a synthesis reaction, this reaction is the opposite of a decomposition reaction.

In a single-replacement and double-replacement reaction, there is an interchange of cations between the reactants, this does not happen in the picture.

If the order of a reaction with the regard to reagent A is 2, when the concentration of A doubles, the rate will

Anarel [89]

Answer:

Rate will double

Explanation:

Since the concentration of A is doubling the rate of reaction will also double, since in this scenario concentration is proportional to rate of reaction. So if the concentration of A were to triple the rate of reaction would also triple.

A sample of water at 100°C is converted to steam after absorbing 820 kJ of heat. How grams of H2O are contained in the sample? A

Varvara68 [4.7K]

Since water is already at 100<span>°C all the energy is used to evaporate it.
Now we can calculate how many </span>mols of water are evaporated with 820kJ.
$N= \frac{820}{41} =20 mol$
We calculated that we got 20 mols of water evaporated. Now, all we have to do is find how many grams is a mol of water. Molar mass of water is <span>20.16 g/mol.
</span>The final answer is:
$m=20*20.16=403.2g$

According to the VSEPR theory, which of the following factors determines the shape of a

Gala2k [10]

Answer:

B only

Explanation:

Using the VSEPR principle, the electron bond pairs and the lone pairs on the middle atom help us predict the structure of the molecule. The shape of a molecule is determined by the position of the nucleus and its electrons. The electrons and the nucleus settle in positions that minimize repulsion and maximize attraction.
