<span>When a chemist mixes oxygen gas and hydrogen gas to form
water, which is composed of one oxygen and two hydrogen atoms per molecule. The hydrogen and oxygen atoms bounds together by making a bond called covalent bond.<span> In a covalent bond, two atoms are bound
together because they each want to "share" each other's electrons.</span></span>
Answer:
An example of geotropism is the movement of nutrients. minerals and water in a plant. This transport is accomplished by specialized parts of the plant, the xylem which is pronounced zylem and the phloem which is pronounced flowem are the straw like parts of a plant’s stem that move the stuff up and down.
Explanation:
It is c I hope I helped out with this question!.
Answer:
addition of HNO3 HNOX3 to Cu - Aueous
addition of H2SO4 HX2SOX4 to CuO - Aqueous
addition of Z n Zn to C u S O 4 CuSOX4 - Solid
addition of N a O H NaOH to C u ( N O 3 ) 2 Cu(NOX3)X2 - Solid
heating of C u ( O H ) - Solid
Explanation:
Copper when introduced with acids form an aqueous solution and fumes are released in air during the chemical reaction. When NaOH is added to copper then solid copper product is released. Copper dissolves on HNO but does not dissolves in HCL.
The core of the atom contains a nucleus. That nucleus is made up of protons and neutrons.
Protons are made up two up quarks and a down quark. Up quarks have a charge of +2/3 and down quarks have a charge of -1/3.
+2/3 + 2/3 -1/3 = +4/3 - 1/3 = +3/3 = +1. This means that protons have a positive charge.
Neutrons are made up of two down quarks and an up quark.
-1/3 - 1/3 + 2/3 = -2/3 + 2/3 = 0. This means that neutrons have no charge, or a neutral charge.
