Select the evidence that supports the big bang theory. (select 3) Question 4 options:

Cosmic radiation shows evidence of an explosion.

Blue-shifted star spectra show evidence the universe is shrinking.

Evidence shows a black hole exists at the beginning of the universe.

Evidence shows the universe is made of mostly hydrogen and helium.

Red-shifted star spectra show evidence the universe is expanding.

In order to calculate the amount of heat transferred you must know the __ and specific heat of the material, as well as the change in temperature. a. volume b. density c. mass d. enthalpy

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Anyone who's in connections academy chemistry b have the factors that affect the rate of a reaction portfolio already done?
