Which particle has the least mass

Chemistry
1 answer:
enyata [817]3 years ago
6 0

Answer:

b. proton

Explanation:

The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.

What is the molarity of 5.60 mol of sodium carbonate in 1500 ml of solution?
FrozenT [24]

Answer:

3.74 M

Explanation:

We know that molarity is moles divided by liters. The first thing to do here is convert your 1500 mL of solution to L. There's 1,000 mL in 1 L, so you need to divide 1500 by 1000:

1500 ÷ 1000 = 1.50

Now you can plug your values into the equation for molarity:

5.60 mol ÷ 1.50 L = 3.74 M

How is a battery and a banana the same when considering energy?
emmainna [20.7K]

A battery and a banana are the same when considering energy:

A battery when connected to a device produces electro-chemical reactions and contains one or more cells. The same thing can be tried out with fruits also. There are many fruits which can be taken into account. A lemon shows less amount of voltage when seen through a multimeter rather than a banana which shows a higher voltage. This was because of the acid present in the a fully ripped banana. The acid is called ascorbic acid. This acid has a higher pH level than compared to the pH of the citric acid found in lemon.  

This shows that a banana plant is not so expensive and reliable for the production of renewable energy and a battery is also inexpensive, reliable and stable.

If an object has a density of 4.2 g/mL, what is its density in hg/L?
alekssr [168]

I believe "h" stands for hecta-, which means "one hundred."

I will convert from g to hg (divide by 100), then from mL to L (multiply by 1000).

\frac{4.2g}{mL}*\frac{1hg}{100g}*\frac{1000mL}{1L}=42\frac{hg}{L}
