Answer:
d = 1.85 g/cm³
Explanation:
Given data:
Volume of sulfuric acid = 35.4 mL
Mass of sulfuric acid = 65.14 g
Density of sulfuric acid = ?
Solution:
1 ml = 1cm³
Formula:
d = m/v
d = 65.14 g / 35.2 cm³
d = 1.85 g/cm³
Answer:
<em><u>Isozymes</u></em>
Explanation:
Isozymes are enzymes that differ in amino acid sequence but catalyze the same chemical reaction. These enzymes usually display different kinetic parameters, or different regulatory properties.
Elements in group 1-2, 13-18, the number of valence electrons is related to the group number. For example, in the first group, the alkali metals there is one valence electron, however in group 13, there are 3 valence electrons. Valence electrons are also known as the outershell electrons.
Answer:
33.3
Explanation:
if we were to add 29.0 of argon and 4.30 of sulfur and that would come out 33.3.
Answer:
You will have 19.9L of Cl2
Explanation:
We can solve this question using:
PV = nRT; V = nRT/P
<em>Where V is the volume of the gas</em>
<em>n the moles of Cl2</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is 273.15K assuming STP conditions</em>
<em>P is 1atm at STP</em>
The moles of 63g of Cl2 gas are -molar mass: 70.906g/mol:
63g * (1mol / 70.906g) = 0.8885 moles
Replacing:
V = 0.8885mol*0.082atmL/molK*273.15K/1atm
V = You will have 19.9L of Cl2
