Answer:
5 would be the large intestine
Explanation:
Here is what i got from my notes, hope this helps.
Mixture components keep their identities.
Mixture components CAN be separated PHYSICALLY
Homogenous Mixture: You CAN NOT the different parts (phases) of the mixture
Heterogeneous Mixture : You CAN SEE the different parts (phases) of the mixture easily
A solution is a HOMOGENOUS MIXTURE of particles so small that they cannot be seen and CANNOT be filtered out
A compound is something that is made from something that can be separated from 2 things.
It is a mixture and has chemical bonds.
Answer:
2Mg(s) + O(g) --> 2MgO
Explanation:
The 2's are the coefficients
(s) = solid
(g) = gas
Hope that helped
Answer:
0.25 mole of CO₂
Explanation:
We'll begin by calculating the mass of oxygen in 1 mole of carbon dioxide (CO₂). This is illustrated below:
Molecular formula of carbon dioxide
=> CO₂
Mass of oxygen in CO₂ = 2O
= 2 × 16
= 32 g
Thus, 1 mole of CO₂ contains 32 g of oxygen.
Finally, we shall determine the number of mole of CO₂ that contains 8 g of oxygen. This can be obtained as follow:
1 mole of CO₂ contains 32 g of oxygen.
Therefore, Xmol of CO₂ will contains 8 g of oxygen i.e
Xmol of CO₂ = 8/32
Xmol of CO₂ = 0.25 mole
Thus, 0.25 mole of CO₂ contains 8 g of oxygen.
Answer:
Burn beeswax candles. They clean the air, produce negative ions, and assist with allergy and asthma reduction. Run an indoor water fountain. The force or energy of falling water causes the neutral particles in air to split which frees electrons to attach to other air molecules resulting in negative ions.
