Explanation:

Answer:

Mass = 96g

Explanation:

Molarity = number of moles/volume of solvent

According to the provided information, volume = 1.55L, Molarity = 1.55M

number of moles (n) = molarity × volume

n = 1.55 × 1.55

n = 2.4025

n = 2.40mol

For NaOH, molar mass = 23 + 16 + 1 = 40g/mol

mole = mass/molar mass

Mass = molar mass × mole

Mass = 40 × 2.40

Mass = 96g

Answer: Thus 44 g of [tex]CO_2[/tex] will be produced  if 30 g of [tex]C_6H_{12}O_6[/tex] were reacted with an excess of oxygen

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} C_6H_{12}O_6 =\frac{30g}{180g/mol}=0.17moles[/tex]

The balanced chemical equation is:  

[tex]C_6H_{12}O_6 +6O_2(g)\rightarrow 6CO_2+6H_2O(g)[/tex]

As [tex]C_6H_{12}O_6[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.

According to stoichiometry :

1 mole of [tex]C_6H_{12}O_6[/tex] produce =  6 moles of [tex]CO_2[/tex]

Thus 0.17 moles of [tex]C_6H_{12}O_6[/tex] will produce=[tex]\frac{6}{1}\times 0.17=1.0mole[/tex]  of [tex]CO_2[/tex]

 Mass of [tex]CO_2=moles\times {\text {Molar mass}}=1.0moles\times 44g/mol=44g[/tex]

Thus 44 g of [tex]CO_2[/tex] will be produced  if 30 g of [tex]C_6H_{12}O_6[/tex] were reacted with an excess of oxygen.

Bright half starts from a new moon day and ends on a full moon day

dark half starts from a full moon day and ends on a new moon day

Answer and Explanation:

The bright half is the side we see and the dark half is the other side.

If you're referring to the moon, the bright half starts on a new moon day and ends on a full moon, whereas on the other hand dark half starts ona full moon and ends in a new moon, kinda like cycle. There are practically the same and have no big astounding differences between them.

Answer:

ω∉1

Explanation:

TB solution = 100.3315 °C

T freezing solution = -1.209 °C

Given

1.2 g glycerol

20 g water

Required

the boiling point

the freezing point

Solution

ΔTB = KB . m

ΔTF = KF . m

mass water = 20 g = 0.02 kg

Kb water = 0.51 °C/m

KF water = 1.86 °C/m

mol glycerol :

= 1.2 g : 92,09382 g/mol

= 0.013

molal  : the number of moles of solute in 1 kg of solvent  

molal of solution :

= 0.013 : 0.02

= 0.65 m

ΔTB = KB . m

ΔTB = TB solution - TB solvent  

TB solution - 100 = 0.51 x 0.65

TB solution - 100 = 0.3315

TB solution = 100.3315 °C

ΔTF = KF . m

ΔT = KF . m

ΔTF = 1.86 x 0.65

ΔTF = 1.209

T_f  = -1.209 °C

Answer:

The correct answer is - alkali or base.

Explanation:

The litmus paper test is used to find whether a solution is basic or acidic. In a litmus paper test, a litmus paper is a dip in a particular or desired solution that turns the color of litmus paper to red, blue, or purple based on the pH of the solution.

If the paper turns red it means the solution is acidic, in a neutral solution it turns to the purple color and if the blue color appears then it is a basic or alkali solution. The solution of baking soda turns litmus paper into blue color which means baking soda is most likely a base.

Explanation:

this is a math equation, not a chemical formula

Answer:

By passing the gas through lime water

Explanation:

The equation of the reaction of vinegar with  calcium carbonate in the form of marble chips is shown below;

CaCO3(s) + 2CH3COOH(aq) ---------> Ca(CH3COO)2(aq) + H2O(l) + CO2(g).

We can see from the reaction equation that the gas produced is carbon dioxide. This gas is identified by passing the gas through lime water. If lime water turns milky, then the gas is truly carbon dioxide.

Explanation:

Prior preparation is required in a location at risk of natural disasters, this includes a communication system and infrastructure aimed at protecting and educating society. Technology is extremely important for the prevention of natural disasters, through forecasting and monitoring systems it is possible to map and analyze the possible risks and anticipate them with the necessary solutions, such as removing a population from a certain location with a risk of drilling.

It is necessary for the population to be aware, understand the alerts and signals issued in case of risk and follow the guidelines of the trained authorities, in this way it is possible to mitigate the effects of natural disasters.

Answer:

D. Philippine Atmospheric, Geophysical and Astronomical Services

Administration (PAGASA)

Explanation:

4.C. 62.0 kph

3) The agency that tracks the activities of typhoon that enters PAR is; D. Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA)

4) The speed of the typhoon is; C: 62 kph

3) PAR simply means Phillipines Area of responsibility.

Now this PAR is an area located at the Northwestern Pacific and it is the place where the Philippines' national meteorological agency called Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) usually monitors the weather occurrences.

This means that the typhoons that enter PAR would also be monitored by PAGASA.

4) we are given;

Distance of Typhoon Grasya from Bislig city; d = 186 km

Time at which landfall is expected; t = 3 hours.

Formula for speed is;

Speed = distance/time

Speed = 186/3

Speed = 62 kph

Answer:

a) Chlorine Trifluoride

b) Dichlorine Heptoxide

GOOD LUCK FOR FUTURE! :)

Answer:

(a) The slope of distance-time graph gives the speed of the objects.

           As the slope of object  (B) is the greatest among all, thus  B has the largest speed and hence it is the fastest among all the objects.

(b)  :      As the curve of the objects do not intersect with each other even once, hence they cannot be at the same point on the road at the same time.

(c)   :      On the y axis  (i.e.  distance line), 7 small represents 4 km

      ∴  1 small line  =  

7

4

​  

=0.57 km

           Position of C at the instant B passes A is  8 km

(d)   ;     Position of B at the instant it passes C is 2nd small line above 4 km i.e. 4+2×0.57=5.14 km  

       ∴ Distance traveled by B   =5.14−0=5.14 kmV

Explanation:

Due to the positive value of the change in temperature, this is an endothermic reaction.

Since the forward reaction is endothermic, increasing the temperature increases the equilibrium constant (k).

In an equilibrium system, the position of the equilibrium will move in a way to annul the change made to the system. An increase in temperature for an endothermic reaction would favour the reaction, leading to increase in amount of products and decrease in amount of reactants.

Answer:

equal to ​

Explanation:

This question is depicting the LAW OF CONSERVATION OF MASS/MATTER, which states that matter can neither be created nor destroyed. Hence, in an isolated system, the original mass of the reactants must be EQUAL TO the final mass of the products formed.

In other words, the law states that no matter the change in chemical composition of the reactants in a chemical process, the mass does not change or it remains constant.

According to the concept of valency, 2 moles of oxygen are needed to react with 100.0 grams of aluminum.

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.
