Answer: C
Explanation:
Sunlight
6 CO2 + 6 H2O --------------> C6H12O6 + 6 O2
Chlorophyll
Carbon(IV)oxide Water Glucose Oxygen
Answer:
A. 1.50
Explanation:
9.01 x 1023 molecules* 1 mol/ 6.022×1023 molecules= 1.49618067087 moles
Rounded would be 1.50
Polar covalent bond- a bond where atoms are unevenly shared due to a larger difference in electronegativity of the bonded elements.
Non-polar covalent bond- These are bonds between elements with a low difference in electronegativity. Electrons are shared equally in these bonds between the elements.
Ionic bonds- have such large difference in electronegativity that they take/give electrons to the element they are bonded to. They do not share electrons at all. Bonds between a non-metal and a metal.
It would be carbon dioxide and water.
hope this helps you
Answer:
Blank 1 - 2
Blank 2 - 4
Blank 3 - 3
Explanation:
The unbalanced chemical equation given in the question is as follows:
Au2O3 → Au + O2
To balance a chemical equation, the number of atoms of each element on both sides of the equation (reactants and product) must be the same. Based on this explanation, the balanced chemical equation is as follows:
2Au2O3 → 4Au + 3O2
- 4 atoms of gold (Au) on both sides
- 6 atoms of oxygen on both sides
Hence, based on the question, blank 1, 2 and 3 are 2, 4 and 3 respectively.
