Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal<span> manner is known as a biped /ˈbaɪpɛd/, meaning "two feet" (from the Latin bis for "double" and pes for "foot").

I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:

The process by which people walk relies on the conversion of chemical energy from food into mechanical energy by muscles. Heat energy cannot be directly used to perform work.

A 0.150 M sodium chloride solution is referred to as a physiological saline solution because it has the same concentration of sa

Anna71 [15]

<h3>Answer:</h3>

2.41 g NaCl

<h3>Explanation:</h3>

We are given the;

Molarity of NaCl = 0.150 M

Volume of the solution = 275.0 mL

We are required to calculate the mass of NaCl solute;

<h3>Step 1: Number of moles of NaCl solute </h3>

Moles are calculated by;

Moles = Molarity × Volume

Therefore;

Number of moles of NaCl = 0.150 M × 0.275 L

= 0.04125 moles

<h3>Step 2: Mass of NaCl solute </h3>

Mass of the compound is given by multiplying the number of moles by the molar mass of the compound.

Molar mass of NaCl = 58.44 g/mol

Therefore;

Mass of NaCl = 0.04125 moles × 58.44 g/mol

= 2.41 g

Thus, the mass of NaCl solute is 2.41 g

Sterling silver contains silver and copper metals. if a sterling silver chain contains 17.6g of silver and 2.40g of copper, what

Bogdan [553]

Answer:- 0.88

Solution:- Masses of silver and copper metals are given and we are asked to calculate the percentage of silver in the alloy.

mass percent of Ag = $(\frac{mass of Ag}{mass of alloy})*100$

Mass of Ag = 17.6 g

mass of Cu = 2.40 g

mass of alloy = 17.6 g + 2.40 g = 20.0 g

Let's plug in the values in the formula:

mass percentage of Ag = $(\frac{17.6}{20.0})*100$

mass percentage of Ag = 88%

So, the mass percentage of silver in sterling silver is 88% and in decimal form it is 0.88.
