The temperature in degree celsius to which the gas was heated is calculated using the Charles law formula
that is V1/T1 =V2/T2
V1=88.2 ml
T1=35 +273 = 308 K
V2=123 ml
T2=?
by making T2 the formula of the subject T2=V2T1/V1
=(123 ml x308 k)/88.2 ml =429.5 K
in degree celsius = 429.5 -273= 156.5 degree celsius
Answer:
A is the only neutral atom there.
Explanation:
It consists of 6 atoms 6 neutrons and 6 electrons which means it is neutral. I am currently in chemistry.
The community with high blood varsity is represented with species richness
<h3>What is a community with high biodiversity?</h3>
A community with high biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.
The number of species per unit area is called Species Richness. If you have more number of species , more will be species richness hence stable will be the ecosystem. More species richness will contribute to increase in biodiversity also which is an important aspect biodiversity conservation.

Answer:
D) Measure 58.44g NaCl, dissolve it into 400ml water, and then top off to 500ml in a volumetric flask.
Explanation:
Step 1: Given data
Molarity (M): 2.00 M
Volume (V): 500 mL = 0.500 L
Molar mass of NaCl: 58.44 g/mol
Step 2: Calculate the required moles of NaCl
We will use the following expression.
n = M × V
n = 2.00 mol/L × 0.500 L
n = 1.00 mol
Step 3: Calculate the mass corresponding to 1.00 moles of NaCl
1.00 mol × 58.44 g/mol = 58.44 g
Step 4: Describe the procedure to prepare the solution
Measure 58.44g NaCl, dissolve it into 400ml water, and then top off to 500ml in a volumetric flask.
