You just have to reduce them until there are no more common factors

C4H10 = C2H5 (divided by 2)
C2H5OH= C2H5OH (not divisible so the molecular formula and empirical formula are the same)
H2S2O8= HSO4 (divide by 2)
B2H6= BH3 (divide by 2)

Calculate the speed.<br><br> 1. If a car travels 800m in 30 seconds how fast is it going?
Alex787 [66]

Answer:

s = 26.7 m/s

Explanation:

Given data:

Distance travel = 800 m

Time taken = 30 sec

Speed of car = ?

Solution:

Formula:

S = d/t

s = speed

d = distance

t = time

by putting values.

s = 800 m/ 30 s

s = 26.7 m/s

Write the net ionic equation for the reaction of aqueous copper(II) chloride with aqueous sodium phosphate. Remember to include
sergeinik [125]

Answer:

3 Cu²⁺(aq) + 2 PO₄³⁻(aq) ⇒ Cu₃(PO₄)₂(s)

Explanation:

Let's consider the molecular equation between aqueous copper(II) chloride and aqueous sodium phosphate.

3 CuCl₂(aq) + 2 Na₃PO₄(aq) ⇒ 6 NaCl(aq) + Cu₃(PO₄)₂(s)

The complete ionic equation includes all the ions and insoluble species.

3 Cu²⁺(aq) + 6 Cl⁻(aq) + 6 Na⁺(aq) + 2 PO₄³⁻(aq) ⇒ 6 Na⁺(aq) + 6 Cl⁻(aq) + Cu₃(PO₄)₂(s)

The net ionic equation includes only the ions that participate in the reaction (not spectator ions) and insoluble species.

3 Cu²⁺(aq) + 2 PO₄³⁻(aq) ⇒ Cu₃(PO₄)₂(s)

Describe the spin of carbon-14's valence electrons and explain how you came about your answer.
Snezhnost [94]

we have to know the spin of valence electrons of carbon-14

There are four unpaired electron which are called as valence electron also.The spin of the four unpaired electron is either upfilled or down filled.

The ground state electronic configuration of C-atom is 1s²2s²2p² and one electron from 2s orbital gets excited to 2p orbital. The elctronic configuration in excited state is 1s²2s¹2p_{x}^{1} 2p_{y}^{1}2p_{z}^{1}.

The electron jumps because half-filled orbitals are more stable. Exchange energy is less than pairing energy.
