Answer:

Acid:

Acids have a sour taste.

Acids change the color of certain acid-base indicates.

Acids react with active metals to yield hydrogen gas

Explanation:

Bases taste bitter, feel slippery, and conduct electricity when dissolved in water.

. Write the balanced equation, then outline the steps necessary to determine the information requested in each of the following:

mafiozo [28]

Answer:

See explanation

Explanation:

a) The equation of the reaction is;

2Na + Cl2 ------>2NaCl

Number of moles of sodium = 10g/23 g/mol = 0.43 moles

If 2 moles of sodium reacts with 1 mole of Cl2

0.43 moles reacts with 0.43 * 1/2 = 0.215 moles of Cl2

Mass = 0.215 moles of Cl2 *71 g/mol = 15.265 g

b) Equation of the reaction;

HgO -> Hg + O2

1.252 moles of HgO 1.252/32 gmol = 0.039 moles

1 mole of HgO yields 1 mole of oxygen hence

0.039 moles of HgO yields 0.039 moles of oxygen

Mass of oxygen = 0.039 moles * 32 g/mol = 1.248 g

c) Equation of the reaction;

2NaNO3 -----> 2NaNO2 + O2

Number of moles of 128 g of oxygen = 128g/32 g/mol = 4 moles

2 moles of NaNO3 yields 1 mole of oxygen

x moles of NaNO3 yields 4 moles of oxygen

x = 8 moles of NaNo3

Mass of NaNO3 = 8 * 85 g/mol = 680 g of NaNo3

Which equation correctly relates kinetic energy mass and velocity

jolli1 [7]

Answer: The equation for kinetic energy is $\frac{1}{2}mv^2$

Explanation:

Kinetic energy is the energy possessed by the virtue of object's motion. It is defined as the work needed to move a body of a given mass from rest to its velocity.

Mathematically,

$K.E.=\frac{1}{2}mv^2$

where,

m = mass of the body

v = velocity of the body.

Hence, above equation relates kinetic energy to the mass and velocity of the body.

Determine how many grams of N2 are produced from the reaction of 8.37 g of H2O2 and 5.29 g of N2H4.

Dmitriy789 [7]

N₂H₄ + 2H₂O₂    → N₂ + 4H₂O

mol = mass ÷ molar mass

If mass of hydrazine (N₂H₄) = 5.29 g
then mol of hydrazine = 5.29 g ÷ ((14 ×2) + (1 × 4))
  = 0.165 mol

mole ratio of hydrazine to Nitogen is 1 : 1
  ∴ if moles of hydrazine = 0.165 mol
then moles of nitrogen = 0.165 mol

Mass = mol × molar mass

Since mol of nitrogen (N₂) = 0.165
then mass of hydrazine    = 0.165 × (14 × 2)
   = 4.62 g

How many moles are represented in 213 grams of sodium bromide , NaBr?

Eduardwww [97]

Answer:

The number of mole represented is 2.07 moles

Explanation:

Using the formula

n = m/Mm

n - mole

m - mass

Mm- molar mass

Since the mass is given to be 213g

So lets calculate the molar mass of sodium bromide (NaBr)

The molar mass of Na = 22.99

Br = 79.904

Molar mass = 22.99+79.904

= 102.894g/mol

Using the formula n = m/Mm

n = 213g/ 102.894g/mol

n = 2.07moles
