Mass number = number of neutrons + number of protons

In a periodic table, or other tables, you find that the atomic number of sulfur is 16. That means it has 16 protons.

Then the number of neutrons = 34 - 16 = 18.

Answer:

1. The skater's kinetic energy decreases as he moves up the ramp. As the skater moves down the ramp, his potential energy decreases

2.Kinetic Energy is the energy of motion. As the skateboard rolls down the ramp it loses potential energy and gains kinetic energy. The total energy of the skateboarder remains constant.

Select the correct equalities for the units shown.
elena-14-01-66 [18.8K]

Answer

1. 1cm=10mm, 1kg=1000g and 12in=1 ft

2. 50mm=5cm

    48 in =4ft

     36ft=12 yd

     2.5m=250cm

     1000mL= 1 L

Explanation

if 1cm=10mm then 5cm=?

5×10=50mm

if 12 in =1ft then 48in=?

48/12 =4 ft

if 1m=100cm, then 2.5m=?

2.5×100= 250cm

and when know from capacity that 1000mL is equivalent to 1 liter.

There are 43.2 g of carbon to 14.4 g of hydrogen in a sample of methane (CH4). What percent of 37.8 g of methane is carbon?
EastWind [94]

Using the law of constant proportions  which says that within the same compound, elements exist in fixed ratios. 

Therefore; we can use the ratio of total mass to the mass of carbon, to determine the amount of carbon in another sample.

Mass C / Mass CH4 = Mass C / Mass CH4

43.2 g / 57.6 g = Mass C / 37.8 g

Mass C = 37.8 g × 43.2 g / 57.6 g 

              = 28.35 g

Hence; the percentage of carbon will be; 

=(28.35/ 37.8 )× 100%

= 75 % 

Thus; 75% of 37.8 g of methane is carbon
