- Standard state refers to
yulyashka [42]

Answer: The standard state refers to 1 atm and 25^{o}C.

Explanation:

It is known that a chemical/substance can either be present in a solid, liquid or gaseous state.

So, when the phase of a substance like solid, liquid or gas is present at 1 atmosphere pressure and at a temperature of 25^{o}C then it known as standard state of substance.

Thus, we can conclude that standard state refers to 1 atm and 25^{o}C.

Baking soda (nahco3) is an active ingredient in some antacids. determine the percent composition of oxygen in baking soda.
telo118 [61]
Assuming the question is asking for percent composition by mass,

The molar mass of sodium bicarbonate is:

22.990 + 1.008 + 12.011 + 3*15.999 = 84.006 g/mol

The molar mass of 3 oxygen atoms is:

3*15.999 = 47.997 g/mol

The percentage composition by mass is:

47.997/84.006 * 100% = 57.1% (3 s.f.)

The digit that would have to be estimated in reading this instrument would be the nearest:
wariber [46]

Answer:

The least count of vernier calipers is 0.01 g.

(B) is correct option.

Explanation:

Given that,

The digit that would have to be estimated in reading this instrument,

According to figure,

We need to calculate the pitch

Using formula of pitch

pitch=\dfrac{distance\ moved}{Number\ of\ complete\ rotation}

Put the value into the formula

pitch=\dfrac{1}{10}

pitch=0.1\ g

We need to calculate the least count of vernier calipers

Using formula of least count

Least\ count=\dfrac{pitch}{number\ of\ vernier\ scale\ division}

Put the value into the formula

Least\ count=\dfrac{0.1}{10}

Least count = 0.01\ g

Hence, The least count of vernier calipers is 0.01 g.

(B) is correct option.
