Answer:

Cu₂O.

Explanation:

copper = 7.298

copper oxide = 8.217

oxygen in copper oxide = .919 g

7.298 g of copper = 7.298 / 63.5 mole of copper

= .1149 mole of copper

.919 g of oxygen = .919 / 16 mole of oxygen

= .0574 mole of oxygen

ratio of mole of copper and oxygen

= .1149 / .0574 = 2

formula of copper oxide = Cu₂O.

How do white blood cells fight pathogens?

jonny [76]

White blood cells work in two ways; they can ingest or engulf pathogens and destroy them by digesting them. White blood cells can also produce antibodies to destroy particular pathogens by clumping them together and destroying them. They also produce antitoxins that counteract the toxins released by pathogens.

What is the temperature (°C) of 1.75 g of O2 gas occupying 4.60 L at 1.00 atm?

julsineya [31]

Given- m= 1.75 g

Now moles of O2 gas= Mass/ Molar mass

n = 1.75/32

V= 2L

P= 1atm

R=0.0821.....Constant

As PV=nRT

=> T=PV/nR

= 1* 2/ (1.75/32)*0.0821 K

= 2*32/1.75* 0.0821 K

= 445.45 K

= (445.45- 273.15) degrees celsius

= 172.30 degrees celsius..... ANSWER
