Answer:

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.

Explanation:

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.

K2Te+ Fe(HCO3)2------> KHCO3 + Fe Te<br> how do you balance the equation?

ololo11 [35]

Hey there!

K₂Te + Fe(HCO₃)₂ → KHCO₃ + Fe + Te

Start by balancing HCO₃ since it's a polyatomic ion.

Two on the left, one on the right. Add a coefficient of 2 in front of KHCO₃.

K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te

Balance K .

Two on the left, two on the right. Already balanced.

Balance Te.

One on the left, one on the right. Already balanced.

Balance Fe.

One on the left, one on the right. Already balanced.

Our final balanced equation:

K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te

Hope this helps!

Question 2 of 50

wolverine [178]

The thermal decomposition of calcium carbonate will produce 14 g of calcium oxide. The stoichiometric ratio of calcium carbonate to calcium oxide is 1:1, therefore the number of moles of calcium carbonate decomposed is equal to the number of moles of calcium oxide formed.

Further Explanation:

To solve this problem, follow the steps below:

Write the balanced chemical equation for the given reaction.
Convert the mass of calcium carbonate into moles.
Determine the number of moles of calcium oxide formed by using the stoichiometric ratio for calcium oxide and calcium carbonate based on the coefficient of the chemical equation.
Convert the number of moles of calcium oxide into mass.

Solving the given problem using the steps above:

STEP 1: The balanced chemical equation for the given reaction is:

$CaCO_{3} \rightarrow \ CaO \ + \ CO_{2}$

STEP 2: Convert the mass of calcium carbonate into moles using the molar mass of calcium carbonate.

$mol \ CaCO_{3} \ = 25 \ g \ CaCO_{3} \ (\frac{1 \ mol \ CaCO_{3}}{100.0869 \ g \ CaCO_{3}})\\ \\\boxed {mol \ CaCO_{3} \ = 0.2498 \ mol}$

STEP 3: Use the stoichiometric ratio to determine the number of moles of CaO formed.

For every mole of calcium carbonate decomposed, one more of a calcium oxide is formed. Therefore,

$mol \ CaO \ = 0.2498 \ mol$

STEP 4: Convert the moles of CaO into mass of CaO using its molar mass.

$mass \ CaO \ = 0.2498 \ mol \ CaO \ (\frac{56.0774 \ g \ CaO}{1 \ mol \ CaO})\\ \\mass \ CaO \ = 14.008 \ g$

Since there are only 2 significant figures in the given, the final answer must have the same number of significant figures.

Therefore,

$\boxed {mass \ CaO \ = 14 \ g}$

In the Penny Lab that we ran, what is the independent variable? Question 1 options: the soap the number of water drops the penny

motikmotik

Answer:

I'd say it's the number of water drops.

Explanation:

The number of water drops is what you're controlling or purposely controlling and that answer choice makes the most sense out of the other answer choices. So I'd say it's "The Number of Water Drops."
