Answer:
Heterogenous
Explanation:
Mud is a mixture of water and soil
Answer:
conclusion
Explanation:
it can't be a hypothesis since tests are carried out to verify so it is not a theory
an introduction to an experiment only gives the basis of what we are investigating therefore nothing has been proven and the question is still unanswered
Electrons = protons
protons = atomic number
protons + neutrons = atomic mass
Therefore: a) protons + 7 = 15
protons= 15 -7
protons= 8
B) Remember proton = atomic number
so atomic number = 8
C)Now we know the atomic number so we can easily check on the periodic table what element has an atomic number of 8, which is Oxygen
Answer:
1.D) CH4 + 2O2 → CO2 + 2H2O
2C)2,1,2
3.D)SIO2 + 4HF → SIF4 + 2H2O
4.D)2As + 6NaOH → 2Na3AsO3 + 3H2
5.C)SiCI4 + 2H2O → SiO2 + 4HCI
Explanation:
equal number of atoms of each elements in both the sides of the chemical equation is required to have an equation in balanced state.
Answer:
Im pretty sure that 5N to the Right is correct answer
