Answer:
0,3457 grams equal to 345.7mg
Explanation:
1000 mg-------1 g
345.7mg------x= (345.7mgx 1 g)/1000mg= <em>0,3457 g</em>
Na₂S₂O₃(aq) + 2HCl(aq) → 2NaCl(aq) + H₂O(l) + SO₂(g) + S(s). A light yellow precipitate develops as the process continues.
<h3>What does the chemistry term "equation" mean?</h3>
Reaction equation are symbolic depictions of chemical reactions where the reactants and products are stated in relation to the following chemical formulae.
<h3>Equation and response are what?</h3>
What is an equations and a chemical reaction? In a chemical change, bonds between molecules of the reagent are destroyed and new bonds between molecules of the product are established to create a new substance. A chemical formula is nothing more than a statement of fact that represents how reactants generate products.

If 45 g of O2 gas in a 500 mL container is exerting a pressure of 5.2 atm, 22.53K is the temperature in the gas.
<h3>What is an ideal gas equation?</h3>
The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
First, calculate the moles of the gas using the gas law,
PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.
Given data:
P= 5.2 atm
V= 500 mL =0.5 L
n=?
R= 
T=?
Moles = 1.40625
Putting value in the given equation:
T= 22.53167034 K= 22.53K
Hence, If 45 g of O2 gas in a 500 mL container is exerting a pressure of 5.2 atm, 22.53K is the temperature in the gas.

So if you are trying to find the coffee with the highest concentration of sugar, the cup that has the highest concentration of sugar is the cup that Sarah made on Thursday.
Since there were sugar molecules remaining at the bottom of her coffee cup, that means that the coffee solution was completely saturated with sugar - no more sugar was able to dissolve in the coffee.
Answer:
6 and 3
Explanation:
"Juanita begins to factor an expression as shown.
x² + 3x − 18 = (x + _) (x − _)
What numbers should be placed in the boxes from left to right?"
Use AC method to factor.
1 × -18 = -18
Factors of -18 that add up to 3 are +6 and -3.
The factors are x + 6 and x − 3.
