Answer:
c)<em> y = 80 (2.5)^x</em>
Explanation:
The first term is 80 and the common ratio is 2.5 because every term is being multiplied by 2.5. To figure this out when it is not
obvious, divide the 2nd term by the first term. The equation is y = 80(2.5)^x
We can check the answers by putting the values in the formula
y = 80(2.5)^1
= 200
y = 80(2.5)^2
= 80 x 6.25
= 500
y = 80(2.5)^3
= 80 x 15.625
= 1250
y = 80(2.5)^4
= 80 x 39.0625
= 3125
Answer:
CH4+2O2→CO2+2H2O
Moles of oxygen=3232=1
Moles of carbon dioxide=4422=0.5
Moles of water=1818=1
1 mole of methane reacts with 2 moles of oxygen to give 1 mole of CO2 and 2 moles of water so 0.5 mole of methane will be required which is equal to 0.5×16=8g.
Explanation:
8g
This is false, a compound does not have to contain both cations and anions if ions are present.
Hey
<span>
a 25.0ml dsmplr og 0.105M HCI was titrated with 31.5ml of NaOH. What is the concentration of the NaOH I got 0.0834M am I correct HCI + NaOH -----> H20 + NaCl 25.0ml HCI x 1L/1000mlx0.105 mol HCI/1L HCI X 1 mol NaOH/ I mol HCI = 0.0834M
