A blacksmith is in the process of making iron horse shoes. Each shoe, mass of 255.15g, is heated to a bright red (816c), hammere

d into shape, and then dropped into water to cool. If the bucket contains 4L of water (4000g) initially at room temperature (23c) what will the final temperature of the iron be? Specific heat of cast iron: 0.461 J/gC. Specific heat of water: 4.18 J/gC

Which will NOT occur when a light tray ray interacts with a smooth pane of glass?
zhuklara [117]

Answer:

B) diffraction

Explanation:

A smooth pane of glass does not diffract light. A light passing through a smooth pane of glass may be absorbed, reflected or transmitted.

Diffraction only occurs with special types of glasses embedded with a diffraction grating and are called super prisms. Diffraction glasses use a a gradient lens which is able to  separate light into all the colors of the rainbow.

Recall that diffraction is the separation of white light into its component wavelengths.

What is the wavelength of a wave with energy equal to 1.528 x 10-13 J? E=hc/LaTeX: \lambdaλ Energy= Measured in Joules h=Plank's
Ulleksa [173]

Answer:

1.301 × 10⁻¹² m

Explanation:

Step 1: Given and required data

  • Energy of the electromagnetic wave (E): 1.528 × 10⁻¹³ J
  • Planck's constant (h): 6.626 × 10⁻³⁴ J . s
  • Speed of light (c): 3.00 × 10⁸ m/s

Step 2: Calculate the wavelength (λ) of the electromagnetic wave

We can calculate the wavelength of the electromagnetic wave using the Planck-Einstein's relation.

E = h × c / λ

λ = h × c / E

λ = (6.626 × 10⁻³⁴ J . s) × (3.00 × 10⁸ m/s) / 1.528 × 10⁻¹³ J

λ = 1.301 × 10⁻¹² m

Why is amniocentesis a more widely used test than cvs?
maw [93]
Higher probability of loss. Chorionic villus sampling (CVS) and Amniocentesis (AC). The prenatal diagnosis technique can be done earlier in fetal development CVS (first trimester --> 10-13 weeks). AC (second trimester --> 16-20 weeks)

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

How do i balance the equation<br><br> CCl4 +SbF3-----&gt; CCl2F2 + SbCl3
zaharov [31]

Answer:

3CCl4 + 2SbF3 → 3CCl2F2 + 2SbCl3

Explanation:

<em>CCl4 +SbF3 → CCl2F2 + SbCl3</em>

<em />

On the left side we have 3 times F, on the right side we have 2 times F

To balance we have to multiply SbF3 (on the left side) by 2

On the right side, we have to multiply CCl2F2 by 3

<em>CCl4 +2SbF3 → 3CCl2F2 + SbCl3</em>

On the left side we have 2x Sb, on the right side we have 1x Sb

So we have to multiply, on the right side, SbCl3 by 2

<em>CCl4 +2SbF3 → 3CCl2F2 + 2SbCl3</em>

On the right side, we have 12 times Cl, on the left side we have 4 times Cl

We have to multiply, on the left side, CCl4 by 3. The balanced equation is:

<em>3CCl4 + 2SbF3 → 3CCl2F2 + 2SbCl3 </em>

If you have 10 protons and 11 neutrons, in a electrically neutral atom, How many electrons would you have?
LUCKY_DIMON [66]

Answer:

Well, you'd have 1 electron more than protons (since there are 10 protons and 11 electrons). So the previously neutral ion has now become an ion with a -1 charge
