How many liters of oxygen gas, at standard temperature and pressure, will react with 35.4 grams of calcium metal? Show all of th
katrin [286]
At STP, P = 1 atm, and T = 0 C
Thus, PV = nRT => V = nR(273). We will use this later...
if you have 35.4 Ca, and the molar mass of Ca is 40.08, you get .883 moles Ca. Thus, since it takes 2 moles of Ca to form a reaction, you only need half the moles of Ca of O2. Thus, n(O2) = .883/2
Tie this back to the first equation and you get
V = .442 * <span>0.082057(which is R) * 273 = 9.9 L</span>

What would happen if BHP changed to 45mmHg and the other pressures remained constant?A. Filtration would decrease, but still fun
Vladimir [108]

Answer:

C. Filtration will cease

Explanation:

Generally, blood hydrostatic pressure (BHP) in the capillaries of human body drives filtration. A significant change in the value of the blood hydrostatic pressure leads to a corresponding change in the rate of filtration. The higher the change in the BHP, the higher the change in filtration and vicer versa. Thus, if BHP changes to 45 mmHg, filtration will cease.

jeyben [28]

Answer:

A. Second

Explanation:

The S.I unit of time is in Seconds.

The S. I unit is known as the metric system is the most commonly used system of reporting scientific measurements in the world today. Other units are the imperial units.

It is the international system of unit used in almost all countries. The seven basic SI units are:

        Quantities                                    Units

  • Length                                         meters(m)    
  • Time                                            seconds(s)
  • Amount of substance                 moles(mol)
  • Mass                                            kilograms(kg)
  • Luminous intensity                     candela(cd)
  • Temperature                               kelvin(K)
  • Electric current                            ampere(A)

The SI unit of time which measures the duration of an activity or event is therefore given as seconds(s)
