Answer : The correct option is, (D) volume

Explanation :

Length : It measures the distance. The SI unit used to measure the length is, Meter (m).

Mass : It measures the weight of an object. The SI unit used to measure the mass is, Kilogram(kg).

Temperature : It measures the amount of heat present in the body. The SI unit used to measure the temperature is, Kelvin(K).

Volume : It measures the amount of space a substance occupies. The SI unit used to measure the volume is, Meter cube (m³).

The other units used to measure the volume are gallon, liter, pint, etc.

Thus, the property of the gas to the chemist report is, Volume.

A student determines measures the mass of one mole of carbon and finds it to be 12.22 grams. if the accepted value is 12.11 gram

Gre4nikov [31]

Answer:-

0.91% is the students % of error

Explanation: -

Accepted value= 12.11 grams

Measured value = 12.22 grams

Error = 12.22-12.11 = 0.11 grams

Percentage error = $\frac{0.11 grams}{12.11 grams}$ x100

= 0.91 %

Thus 0.91% is the students % of error

According to the law of conservation of mass in a chemical reaction the total starting mass of all the reactants equals the tota

Ber [7]

I believe the correct answer true. According to the law of conservation of mass, in a chemical reaction the total starting mass of all the reactants equals the total final mass of all the products. This law states that mass cannot be created or be destroyed. So, the total mass that goes in a process should be equal to the mass that goes out the process. This is true for chemical reactions and physical processes. It is Antoine Lavoisier who described this and is a basic principle used in physics and in chemistry. Mass, unlike energy, cannot be transformed to any form so however the transformation happens the mass should be constant.

If excess caso4(s) is mixed with water at 25 ∘c to produce a saturated solution of caso4, what is the equilibrium concentration

Ray Of Light [21]

Answer:

The equlibrium concentration sof Ca+2 ion willl be 4.9×10∧-3 M

Data Given:

Ksp of CaSO4 = 2.4 × 10∧-5

CaSO4 ⇔ Ca+2 + SO4∧-2

Solution:

Ksp = [Ca+2].[ SO4∧-2]

2.4 × 10∧-5 = [x].[x]= x²

x = 4.9×10∧-3 M

Result:

The conc. of Ca+2 ion is 4.9×10∧-3 M

shtirl [24]

5 plates is the highest amount that can be served

There’s only 5 sandwiches so 7 is automatically ruled out, there’s 14 corn cobs and 5 sandwiches only need 10 so it works out
