As part of a lab experiment, Tasha drops a metal cube into a beaker of water, as shown in the figure below. heat transfer After energy in the form of heat transfers between the substances, what is the final temperature of the water? Group of answer choices The final temperature is 25 °C because there is more water than metal. The final temperature is 50 °C because the metal warms the water to the temperature of the metal. The final temperature is between 25 °C and 50 °C because most of the thermal energy is lost to the air around the substances. The final temperature is between 25 °C and 50 °C because energy is transferred from the metal to the water.

all eukaryotic cell have mitochondria : )

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
