Answer:

the force has to increase aswell

Explanation:

force and mass have a direct relationship meaning when one increases the other will. the heavier something is, the more force u have to put in order to get it to move!!

He balanced equation for the reaction of acetylene, c2h2, and oxygen in an acetylene torch is 2 c2h2 + 5 o2 → 4 co2 + 2 h2o. in
pickupchik [31]
Answer: 0.4 g

Explanation:

1) Balanced chemical equation:

2) 2C2H2 + 5 O2 → 4CO2 + 2 H2O

3) mole ratios:

2 mol C2h2 : 5 mol O2

4) Convert 0.13 g C2H2 into number of moles

n = mass in grams / molar mass

molar mass C2H2 = 2 *12g/mol + 2*1 g/mol = 26 g/mol

n = 0.13 g / 26 g/mol = 0.005 mol

5) Set the proportion with the unknown

5 mol O2             x
----------------- = ---------------
2 mol C2H2      0.005 mol C2H2

x = 0.005 mol C2H2 * 5 mol O2 / 2 mol C2H2 = 0.0125 mol O2

6) Convert 0.0125 mol O2 to grams

mass = number of moles * molar mass

molar mass of O2 = 32 g/mol

mass = 0.0125 mol * 32 g/mol = 0.4 g

Answer: 0.4 g

How many triple points are in the phase diagram below:
solong [7]

Answer: There are 3 triple points in the given phase diagram.

Explanation: Triple point is defined as the point at which the temperature and pressure of the 3 phases are in equilibrium with each other.

In the given phase diagram, there are three points which is satisfying this definition.

Point A: At this point The monoclinic form and rhombic form have the same vapor pressure. Hence,

Rhombic(s) \rightleftharpoons Monoclinic(s) \rightleftharpoons Vapor(g)

Point B: At this point, the monoclinic form starts to melt. Hence,

Rhombic(s) \rightleftharpoons Liquid(l) \rightleftharpoons Vapor(g)

Point C: At this point, the rhombic form, monolinic form and liquid is in equilibrium. Hence,

Rhombic(s) \rightleftharpoons Monoclinic(s) \rightleftharpoons Liquid(l)

Hence, this system has 3 triple points.

How many valence electrons are represented in the following electron configuration? 1s22s22p5
dalvyx [7]
The element above has 7 (OPTION D) valence electrons.  This is because on the second shell, two electrons occupy the S orbital of the second shell (2s²)and five occupy the P orbital (2p⁵) , for a total of 7 valence electrons (1s² 2s²  2p⁵)

To what volume should 11.9 mL of an 8.00 M acetic acid solution be diluted to obtain a final solution that is 1.50 M?
artcher [175]
Use M1V1 = M2V2
11.9(8) = 1.5V2
95.2 = 1.5(V2)
V2 = 63.5 mL
