Please guys help me my quiz is timed and i dont have a lot of time left PLEASSE HELP ME!
tatyana61 [14]

Answer:

I think these are it

Explanation:

The amount of current is the same at every point in a series circuit.

All of the parts of a series circuit—power source, wires, and devices—are connected along the same pathway

If one device in a series circuit burns out or is disconnected, the entire circuit is broken

The electrons have multiple pathways to travel.

Each time there is damage (break) in any one of the resistors the entire circuit will not function.

PLEASE HELP- I WILL GIVE BRAINLIEST AND THANKS

Answer:

The mass of 10 cm³of a 0.4 g/dm³ solution of sodium carbonate is 0.004 grams

Explanation:

The question is with regards to density calculations

The density of the given sodium carbonate solution, ρ = 0.4 g/dm³

The volume of the given solution of sodium carbonate, V = 10 cm³ = 0.01 dm³

Density \ of \ an \ object, \rho  = \dfrac{The \ mass \ of \ the \ object, \ m }{\ The \ volume \ of \ the \ object, \ V }

\rho = \dfrac{m}{V}

Therefore, we have;

The \ Density \ of \ the \ sodium \ carbonate, \ \rho  = 0.4 \ g/dm^3 =  \dfrac{m }{ 0.01 \ dm^3 }

The mass, "m", of the sodium carbonate in  = ρ×V = 0.4 g/dm³ × 0.01 dm³ = 0.004 g

The mass of 10 cm³ (10 cm³ = 0.01 dm³) of a 0.4 g/dm³ solution of sodium carbonate, m = 0.004 g.

cyclohexanol is burned as a fuel, according to the following equation, how many moles of oxygen are needed to produce 13.7 mol o
lidiya [134]

 The moles  of oxygen  that are needed  to produce 13.7 moles  of  carbon  dioxide  is  21.17  moles  of Oxygen


<u><em>calculation</em></u>

2 C₆H₁₂O  + 17 O₂ → 12 CO₂  +12 H₂O


The moles of O₂  is determined using the mole ratio

that  is for  given equation above   O₂ : Co₂  is 17 :12

therefore the moles of O ₂= 13.7   moles x 17/12 =21.17  moles

In a Lewis structure, why must pairs of unshared of lone pairs if dots be placed around the outside of some of the atoms
Maksim231197 [3]

Answer:

In a Lewis symbol, the symbol for the element is used to represent the atom and its core electrons. Dots placed around the atom are used to indicate the valence electrons. ... In 1916, Gilbert Newton Lewis, an American chemist, suggested that molecules were formed when atoms shared pairs of outer electrons.
