Answer:
1.225g
Explanation:
From the question given,
Volume of diamond = 0.35cm^3
Density of diamond = 3.5g/cm^3
Mass of diamond =?
Density = Mass /volume
Mass = Density x volume
Mass = 3.5 x 0.35
Mass of diamond = 1.225g
Answer: d
Explanation:it’s physics no so hard
Orbital s is always the first one to fill up
Answer:
B. More reactant is added.
Explanation:
The question basically asks at which condition would the forward reaction be favoured.
The law of equilibrium states when a system at equilibrium is disturbed by, it would annul that change. In order to increase the forward reaction, more of the reactant should be added. In order to annul this change, the system would have to favour the reaction that deals with reducing the amount of reactant added.
The correct option is;
B. More reactant is added.
Answer:
The volume is 77 L.
Explanation:
where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature in Kelvins.
The current STP temperature is 0∘C or 273.15 K (used for gas laws), and the pressure is 105Pa, which most people write as 100 kPa (both pressures are equal).
