An adult wild mouse has 40 chromosomes. It will have chromosomes in its sperm cells. A mouse zygote will have chromosomes.

Yes i think so not 100 percent sure though

It would be true sodium reacts with water in a violent way 

The answer is d. hope i !

The reaction 2kalsi3o8 + 2(h+ + hco3-) + h2o  →  al2si2o5(oh)4 + 2k+ + 2hco3- + 4sio2 shows that feldspar kalsi3o8 is chemically altered by hydrolysis to form chalky-looking clay mineral kaolinite al2si2o5(oh)4. the chemical breakdown of potassium feldspar due to exposure to acidic water results to the mineral binding with the water molecule to become kaolinite with silica and potassium and bicarbonate ions in solution.
