Answer:

But why should it even matter?

Explanation:

Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object.

The Mass of an object doesn't change when an object's location changes. Weight, on the otherhand does change with location.

Hope this helps!!

Answer:

Matter is measured in mass and not weight because

W=mg

Where m is mass and g is acceleration due to gravity

So we measure matter in mass because it only occupies space and there is no affect of acceleration due to gravity on it

Calculate the molar concentration of the Br⁻ ions in 0.065 M MgBr2(aq).

steposvetlana [31]

MgBr2(aq) is an ionic compound which will have the releasing of 2 Br⁻ ions ions in water for every molecule of MgBr2 that dissolves.
MgBr2(s) --> Mg+(aq) + 2 Br⁻(aq)
[Br⁻] = 0.065 mol MgBr2/1L × 2 mol Br⁻ / 1 mol MgBr2 = 0.13 M
The answer to this question is [Br⁻] = 0.13 M

Two protons and two neutrons are released as a result of this reaction.

Murljashka [212]

Answer: The particle released in the given reaction is one alpha particle

Explanation:

In a nuclear reaction, the total mass and total atomic number remains the same.

For the given fission reaction:

$^{222}_{86}\textrm{Rn}\rightarrow ^A_Z\textrm{X}+^{218}_{84}\textrm{Po}$

To calculate A:

Total mass on reactant side = total mass on product side

222 = A + 218

A = 4

To calculate Z:

Total atomic number on reactant side = total atomic number on product side

86 = Z + 84

Z = 2

The isotopic symbol of unknown element is $_{2}^{4}\textrm{He}$ . Another name of helium atom is alpha particle.

Hence, the particle released in the given reaction is one alpha particle

PLEASE HELP!! EXPLAIN YOUR ANSWER PLEASE! :)

The formula for force is F=ma. Because weight is a measure of force, then we can substitute the weight of the meteor, 3204 N, for F in the the equation for force. We also know that the acceleration of gravity on Earth is 9.8 m/s^2. To find the mass, simply divide both sides of the equation by the value of acceleration to get
$m = \frac{f}{a} = \frac{3204}{9.8} = 326.9$
Therefore, the value of the mass of the meteor is 326.9 kg.
