Yes
The accuracy to which we can measure a value using a given instrument is dependent on the instrument's least count. The least count of this instrument is 0.1 grams, or a tenth of a gram. Therefore, we may measure to the tenth of a gram with confidence. We cannot measure to the hundredth of a gram however.
Answer:
The Sun releases energy by fusing four hydrogen nuclei into one helium nucleus.
Explanation:
nuclear energy
<u>Answer:</u> The new volume will be
<u>Explanation:</u>
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
(at constant temperature)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Hence, the new volume will be
Answer:
A
Explanation:
since Mg has a charge of +2 and ClO3 has a charge of 1-, you need 2 ClO3 to cancel out the +2 since 2 ClO3 ions would have a 2- charge
Answer:
The sodium nitrate is more economical
Explanation:
Hi, to compare this two options you need to determine the amount of nitrogen per 100 lb of both and then estimate its cost:
1) Sodium nitrate
This fertilizer has 30 % by weight of sodium nitrate:
The molecular weight of sodium nitrate:
So, this salt has 14 g of N per 85 g:
Cost per gram:
2) Ammonium sulfate
This fertilizer has 20 % by weight of ammonium sulfate:
The molecular weight of ammonium sulfate:
So, this salt has 14 g of N per 114 g:
Cost per gram:
