Which of the following pairs of microbe classification terms and optimal growth temperatures is mismatched? thermophile – growth at 37°C psychrophile – growth at 15°C psychrotroph – growth at 20-30°C mesophile – growth at 25-40°C hyperthermophiles – growth at greater than 80°C

Astudent uses universal ph paper to find the ph of three solutions . solution a has a ph of 5 solution b has a ph of 11 and solution c has a ph of 7 identify which solution is acidic which solution is neutral and which solution is basic

The zinc within a copper-plated penny dissolves in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can reach the zinc). the reaction between the acid and the zinc 2h+(aq)+zn(s)→h2(g)+zn2+(aq) . when the zinc in a certain penny dissolves, the total volume of gas collected over water at 25 °c is 0.947 l at a total pressure of 743 mmhg . (vapor pressure of water is 23.78 mmhg at 25 °c .) what mass of hydrogen gas is collected? answer in appropriate significant figures

What is the mass in grams of 0.94 moles of sodium bicarbonate, nahco3?
