<h3>What is the acid in lemon juice?</h3>

The main acid in lemon juice is citric acid.

Citric acid is a tricarboxylic acid and will react with baking soda to form a salt and water.

The equation of the neutralization reaction is shown below:

HOC(CO₂H)(CH₂CO₂H)₂ + Na₂CO₃ ----> HOC(CO₂Na)(CH₂CO₂Na)₂ + H₂O

In conclusion, the neutralization of citric acid in lemon juice produces a salt and water.

In 200 g of a concentrated solution of 70.4 wt% nitric acid (r = 1.41 g/mL, FW(HNO3) = 63.01 g/mol), how many grams of water are
mars1129 [50]

Answer:

59.2 grams

Explanation:

We are given that 70.4% of the weight of the total 200 g of the concentration is made up of nitric acid, the remaining information is not required to solve the problem. Since water and nitric acid are the only components of the solution, the total weight of water is given by:

W = 200*(1-0.704)\\W=59.2\ g

There are 59.2 grams of water in this solution.

Synthesis of acetic acid from acetylene
devlian [24]
Acetylene can be converted into acetic acid in 2 steps:

1. reaction of acetylene with water (in the presence of sulphuric acid, and mercuric sulphate as catalysts) to produce acetaldehyde.

2. acetaldehyde is then oxidized (with potassium dichromate for example) to produce acetic acid.

this overall reaction is given by the following equation:

Which organisms in this food web are carnivores? Select the two correct
LUCKY_DIMON [66]

The two correct options are Poison dart frog and Boa constrictor. Both these organisms are pure carnivores which are also known as pure meat eaters in the food web. Carnivores are organisms in the food chain that only meat-eaters and never take any type of vegetation in their diet.

Explanation:

  • A Poison dart frog purely survives on meat (meat- eater).
  • Long sticky tongues are used to catch their prey such as ants, flies, insects.
  • Since they produce high toxin levels, it has very few predators in the wild.
  • Boa constrictor is also an organism that eats only meat.
  • While they are young they eat prey like rats, squirrels and mice.
  • The type of attack used by a boa constrictor is an ambush attack type. It attacks its preys using the surprise factor.
