Answer:

Difficult Question but I would say no

Explanation:

I say no because the whole premise of a chemical reaction is the reaction to new bonds and bond losses happening due to the introduction of a new substance. If the substance hasn't changed at all, it wouldn't be a chemical reaction because their would be nothing reacting.

Answer:

I will give up the electrons

Explanation:

Consider the following rules:

1. An atom loses electrons if its oxidation number is positive.

2. An atom gains electrons if its oxidation number is negative.

3. An atom neither gains nor loses electrons if its atomic number is zero.

As I have an oxidation number [tex]+2[/tex] that is oxidation number is positive, so, I will give up electrons.

Answer:

Multicellular

they are single celled

Answer:

ok so you would just weigh 125 because 16 oz is 1 pound

Explanation:

Answer:

Explanation:

Using Charles Law ,

[tex]\frac{V1}{T1}=\frac{V2}{T2}[/tex]

Using this formula we have ,

V1= 200cm^3

T1=40+273.15 = 313.15 K

T2 = 100+273.15 = 373.15 k

V2= ?

Hence using above formula simplify it we will get ,

V2 = 238.3 cm^3

Answer:

Because the melting of ice as a spontaneous process (or reaction).

Explanation:

Here is an example:

Take a ice on a plate and leave it for half an hour (conditions). After half an hour, we notice water instead of ice.

This process took place without any intervention from your side. Heat absorbed by the ice from surrounding is due to set of conditions not due to your intervention.

So, we can consider melting of ice as a spontaneous process (or reaction).

Answer:

V= 21 cubic cm (( I am not sure about density ))

Explanation:

V= L×W×H

Number of moles =0.52 moles

The number of moles is defined as the ratio between given mass and molar mass.

Given:

Mass of PbSO₄ = 158.1 grams

To find:

Number of moles=?

Molar mass of PbSO₄ =  303.26 g/mol

[tex]\text{Number of moles}= \frac{\text{Given mass}}{\text{Molar mass}}\\\\\text{Number of moles}= \frac{158.1}{303.26}\\\\ \text{Number of moles}= 0.52\text{ moles}[/tex]

Thus, the number of moles it contain will be 0.52.

117 millimeters = 0.117 meters

Explanation:

This is using unit conversions. There are 1000 millimeters in 1 meter, so you would divide your starting value, 117 millimeters by 1000 millimeters. The units will cancel because they are being divided by themselves and you are left with 0.117 meters.

Answer:

Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass. Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons.
