n=PV/RT

convert:

740 torr to atm (1 atm=760 torr)

50 degree celsius to kelvin ( degree celsus +273= kelvin)

n=(0.9737 atm)(12.5L)÷(0.08206 L atm mol ⁻¹k⁻¹) (323 K)

n=0.4592 mols×22.4 L/1 mol.   (22.4 L STP= 1 mol)

=10.286 L at STP

it could be this

Calculate the energy provided by a slice of bread containing 2 g of protein, 1 g of fat, and 20 g of carbohydrate. record your a
vichka [17]
 the energy gained by proteins and carbohydrates differs from the energy gained by fats.
proteins and carbohydrates both give 4 kcal per gram 
fats give 9 kcal per gram
mass of proteins - 2 g
energy given by proteins - 2 g x 4 kcal/g = 8 cal
mass of carbohydrates - 20 g 
energy given by carbohydrates - 20 g x 4 kcal/g = 80 cal
mass of fat - 1 g 
energy given by fat - 1 g x 9 kcal/g = 9 cal
total energy = 8 + 80 + 9 = 97 kcal
energy = 97 kcal

What happens to a line when the y-intercept is changed? Check all that apply.
tamaranim1 [39]

Answer:

As the y-intercept increases, the graph of the line shifts up;

As the y-intercept decreases, the graph of the line shifts down

Explanation:

There are two ways to think about this problem. The first way would be the graphical approach:

  • if we only change the y-intercept, this means we keep the same slope;
  • y-axis is the vertical axis;
  • if we change the point at which the line crosses the y-axis, we either shift it upward for a higher y-intercept or downward for a lower y-intercept.

Now, thinking algebraically, a line has the following equation in a general form:

y = mx + b

The y-intercept is essentially obtained when x = 0, then:

y = b:

  • if we increase b value, the y value increases, so the graph shifts upward;
  • if we decrease b value, the y value decreases, so the graph shifts downward.

Is barium nitrate more soluble in water than CH4 or the other way around?
kenny6666 [7]
Barium nitrate and methane (CH4) are both soluble. They both will dissolve in water, however, barium nitrate will dissociate becoming barium 2+ ions and nitrate becoming NO3 1- ions. All nitrates are soluble and dissociate. CH4 is a weak base and does dissolves but doesn't dissociate. So in solubility terms.... they are both equally soluble just one happens to dissociate into its cations and anions. Hope this helps!
