Answer:
691.7 mmHg is the resulting pressure
Explanation:
Tha Gay-Lussac's law states that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:
P1T2 = P2T1
<em>Where P is pressure and T asbolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Computing the values of the problem:
T1 = 273 + 25 = 298K
P1 = 755.0mmHg
T2 = 273 + 0 = 273K
P2 = ?
755.0mmHg*273K = P2*298K
<h3>691.7 mmHg is the resulting pressure</h3>
The answer is 33.33 %
The explanation:
According to the reaction equation:
MgCO3(s) + 2HCl (aq) --> MgCl2(aq) + H20(l) + CO2(g)
we can see that 1 mole of MCO3 will produce → 1 mole of CO2
-Now we need o get number of mole of CO2:
and when we have 0.22 g of CO2, so number of mole = mass / molar mass
moles = 0.22 g / 44 g/mol = 0.005 mole
∴ moles of Mg = moles of CO2 = 0.005 mole
∴ mass of Mg = moles * molar mass
= 0.005 * 84 /mol = 0.42 g
∴ Percent of MgCO3 by mass of Mg = 0.42 g / 1.26 * 100
= 33.33 %

Answer:
It is known as asymmetric key cryptography it is also called public key cryptography.
Explanation:
Asymmetric key cryptography method makes use of two keys.One is used for encryption and the second one for decryption. The public key serves to encrypt plain text or verify a digital signature, while the private key is used to decrypt or decipher the encrypted text or to create a digital signature.
