How many moles of baso4 are formed if 0.5 moles of na2 so4 react with 60 g of bacl2? na2 so4 + bacl2 → baso4 + 2nacl

0.29

Explanation:

To calculate the moles, we use the equation:

Putting values in above equation, we get:

Moles of = 0.5 moles

According to stochiometry, 1 mole of reacts with 1 mole of

Thus 0.29 moles of will react with 0.29 moles of

Thus is the limiting reagent as it limits the formation of products and is the excess reagent.

1 mole of produces = 1 mole of

0.29 moles of will produce= 0.29 moles of

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
