Answer: carbon dioxide gas is the reactant in the chemical reactions of photosynthesis.

Explanation:

When plants make their own food with the help of sunlight, carbon dioxide and water then the process is known as photosynthesis.

Therefore, carbon dioxide gas is the reactant in the chemical reactions of photosynthesis.

The equation for photosynthesis reaction is as follows.

$6CO_{2}+6H_{2}O+lightenergy \overset{photosynthesis}{\rightarrow}C_{6}H_{12}O_{6} + 6O_{2}$

Determine the mass in grams of 4.69 x 1021 atoms of barium. (The

Virty [35]

Answer:

1.07 g Ba

Explanation:

Hello there!

In this case, according to the definition of the Avogadro's number and the molar mass, it is possible to say that 6.022x10^{23} atoms of barium equal one mole, and at the same time, 1 mole equals 137.327 grams of this element; thus, it is possible to say that 6.022x10^{23} atoms of barium have a mass of 137.327 grams; therefore, it i possible for us to calculate the required mass in grams as shown below:

$4.69x10^{21}atoms*\frac{137.327gBa}{6.022x10^{23} atoms} \\\\=1.07gBa$

Best regards!

consider the titration of hclo4 with koh. what is the ph after 17.0 ml of 0.15 m koh has been added to 15 ml of 0.20 m hclo4?

bezimeni [28]

The ph after 17.0 ml of 0.15 m Koh has been added to 15 ml of 0.20 m hclo4 is 3.347.

Titration is a commonplace laboratory technique of quantitative chemical analysis to determine the attention of an identified analyte. A reagent, termed the titrant or titrator, is ready as a trendy answer of recognized awareness and extent.

Calculation:-

Normality of acid Normality of base

= nMV nMV

= 1 × 0. 15 × 0.017 1 × 0. 20 ×0.015 L

= 2.55 × 10⁻³ = 3 × 10⁻³

The overall base will be high

net concentration = 3× 10⁻³ - 2.55 × 10⁻³

= 0.45 × 10⁻³

= 4.5× 10⁻⁴

pH = -log[4.5 × 10⁻⁴]

= 4 - log4.4

= 3.347

A titration is defined as 'the manner of determining the amount of a substance A by using adding measured increments of substance B, the titrant, with which it reacts till precise chemical equivalence is completed the equivalence factor.

What are some similarities between sublimation and deposition?

Korolek [52]

Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase. Deposition: the substance changes directly from a gas to a solid without going through the liquid phase.
