Students are designing an experiment to test the law of conservation of mass using the following materials: 10 g baking soda, 30

GaryK [48]

Answer:

1. Students need to measure masses of the items.

2. Put baking soda and vinegar in a plastic bag and close it.

3. Mix the two, allowing for a reaction to occur.

4. Figure the mass of the plastic bag while the two components are inside.

5. The combined mass should be equal to what each weighed on their own.

Find the equation of the line passing through the points (2, 1) and (5, 10).

Vedmedyk [2.9K]

The equation : y=3x-5

<h3>Further explanation </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

General formula

y-y1 = m(x-x1)

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

Gradient

$\tt \dfrac{10-1}{5-2}=3$

Equation

$\tt y-1=3(x-2)\\\\y-1=3x-6\\\\y=3x-5$

A balloon is filled to a volume of 1.50 L with 3.00 mol of gas at 25 C. with pressure and temperature held constant, what will b

bixtya [17]

Answer:

3.2L

Explanation:

PV=nRT

since pressure and temperature are held constant we have V=nR

R is a constant also,

Thus; $\frac{v1}{n1}=\frac{v2}{n2}$

v1=1.5L , n1=3mol, n2=1.4mol

$\frac{1.5}{3}=\frac{v2}{1.4}$

v2= $\frac{1.5}{3}*1.4$

v2=3.2L
