Explanation:
Metals react with oxygen to form basic oxides while they react with water to form alkaline solutions. Also, acidic oxides are oxides of nonmetals and they react with water to form acidic solutions.
Trends on the period table shows the variation of metallic character as you move across and down the periodic table. Metallic character of a element decreases across the period on the periodic table from left to right because atoms readily accept electrons in their outermost shell to form stable configurations. Metallic character increases as you move down the group in the periodic table and this is because electrons become easier to lose as the atomic radius increases (more outer shells are added), where there is decreasing attraction between the nucleus and the valence electrons.
So down the group, the acidity of oxide reaction with water decreases because the oxides are more basic down the group while across the period, the acidity of oxide increases because acidic oxides are formed as we move across the period.
I just did this question a few weeks ago.
This is what I put and I got all the points
<span>You first mix salt and sand together in a jar and add water. You then mix it all together and let the salt fully dissolve in the water and let the sand settle and the bottom. You then filter the sand in a different cup. You filter it out with a paper filter and a filter. You put the paper in the filter to catch all the sand and have only the salt water. When you are done filtering it you put the salt water on a burner and let the water evaporate until you only have salt.</span>
Answer:
answer will be b
Explanation:
mole is given 0.20
you have to find mass so just convert it into mass
remember if you move away from mole you multiply and if you move towards mole you divide so
just multiply mole with molar mass of glucose
so
0.20×180 = 36 grams
