Answer: carbon dioxide and water
Explanation:
C3H8 + 5O2 —> 3CO2 + 4H2O
Answer:
the answer will be lithium bromide + sodium
Explanation:
because displace sodium from bromine there by liberating sodium as an element in the product side
D. Zinc metal (zn)
Zinc is a chemical element with atomic number 30.
87.5 I believe because it needs 2.5 L and we multiply 35 by 2.5 because 1 liter needs 35 grams
Answer: 3.42 moles CO = 84.0g, is not true.
Explanation:
Moles is given by the formular; Mass / Molar Mass.
Therefore; 0.2 moles O2 = 6g is true when we multiply 32g x 0.2 = 6g approximately.
0.75 moles H2CO3 = 47g.
Molar formular for H2CO3 = 2 + 12 + 48 =62g.
If we multiply 62g (molar mass ) by 0.75moles, it gives us 47g approximately.
3.42 moles CO = 84g
molar mass of CO = 12 + 16 = 28g
Multiply 28g x 3.42 moles = 95.76g, which is not true.
