Answer:
increased
Explanation:
Consuming a compound increases the concentration. When you increase the concentration, the rate constant for that reaction also increases.
Answer:
D. the sea of electrons
Explanation:
Metallic bonds are defined as the bonds formed between two or more metals. Silver atom form metallic bond with other silver atoms.
In metallic bond, the free electrons or valence electrons present in s and p orbitals delocalize. The valence electrons do not move around the atoms or enter the atoms whereas they form a sea of electrons in which they surround the nuclei (positively charged) of the metal ions interacting. The valence electrons are then freely move in the space between the atomic nuclei.
Hence, the correct answer is "D. the sea of electrons".
Answer:
C help stop bleeding
Explanation:
Platelets stop bleeding by clumping and forming plugs in blood vessel injuries
The empirical formula of the compound is SiCl₄.
<h3>Empirical formula of the compound</h3>
mass of silicon = 28 g/mol
mass of chlorine = 35.5 g/mol
<h3>molar ration: </h3>
Si = 8.56/28 = 0.306
Cl = 43.2/35.5 = 1.216
<h3>Combining ratio</h3>
Si = 0.306/0.306 = 1
Cl = 1.216/0.306 = 4
empirical formula = SiCl₄
Thus, the empirical formula of the compound is SiCl₄.

Answer:
852g
Explanation:
From the question given, we obtained the following information:
Molarity = 3M
Volume = 2L
Mole =?
First, we need to find the number of mole of Na2SO4 present in 2L of the solution. This is achieved by doing the following:
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 3 x 2 = 6moles
Next, we'll find the molar mass of Na2SO4, as illustrated below:
Molar Mass of Na2SO4 = (23x2)+32+(16x4) = 46 + 32 + 64 = 142g/mol
Recall:
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass = 6 x 142 = 852g
