Help please!!!! I dont understand how to tell if it is single replacement or double replacement.

Answers

This is a single replacement. Because Zn flips with H, there is only one -ion (C2H3O2). C2H3O2 also known as Acetate looks different when it bonds with Zn, that’s why it looks different (CH3COO)2 on the product side.
Single: A + BC —> AC + B
Double: AB + CD —> AD + BC
Zn is you A, H is your B, C2H3O2 (Acetate) is your C.

Convert 43.0 grams of SiH4 to moles

Answers

The number of moles in the 4.30 g of SiH₄ is 1.338 moles.

What are moles?

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

To calculate the moles

The molar mass of SiH₄ is 32.12 g

The mass of SiH₄ is 43.0 g

$\rm Number\;of \;moles= (mass)/(molar\;mass)\n\n\rm Number\;of \;moles= (43.0)/(32.12) = 1.338\; mol$

Thus, the number of moles in the 4.30 g of SiH₄ is 1.338 moles.
